But you must admit it's a stonking line!
I am sure that you are aware of the problem of
Groupthink.
Janis has documented eight symptoms of groupthink:
1. Illusion of invulnerability –Creates excessive optimism that encourages taking extreme risks.
2. Collective rationalization – Members discount warnings and do not reconsider their assumptions.
3. Belief in inherent morality – Members believe in the rightness of their cause and therefore ignore the ethical or moral consequences of their decisions.
4. Stereotyped views of out-groups – Negative views of “enemy” make effective responses to conflict seem unnecessary.
5. Direct pressure on dissenters – Members are under pressure not to express arguments against any of the group’s views.
6. Self-censorship – Doubts and deviations from the perceived group consensus are not expressed.
7. Illusion of unanimity – The majority view and judgments are assumed to be unanimous.
7. Self-appointed ‘mindguards’ – Members protect the group and the leader from information that is problematic or contradictory to the group’s cohesiveness, view, and/or decisions.
